PERFORATED SHEET.

Specification of Letters Patent.

Patented Feb. 20, 1917.

Original application filed August 23, 1910, Serial No. 578,579. Divided and this application filed October 10, 1911. Serial No. 653,815.

To all whom it may concern:

Be it known that I, PAUL B. KLUGH, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in' Perforated Sheets, of which the following is a full, clear, concise, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.

My invention relates to perforated sheets such as are used in player pianos, piano players and similar instruments, and also used in machines for cutting or perforating such sheets.

The object of the invention is to provide a perforated sheet capable of use and of ac complishing certain desired results in con nection with certain special forms of tracker boards, and also in connection with certain special types of perforating or punching machines.

In the accompanying drawings Figure 1 is a View of a perforated sheet employed as a music sheet in a piano player or player piano, showing the music rolls and tracker board in addition to the perforated sheet;

Fig. 2 is a View of a portion of the music I sheet itself;

Figs. 3, 4E and 5 are views of small parts of modified forms of music sheet;

Fig. 6 is a vertical section of a machine for cutting perforated sheets of the character referred to;

' Fig. 7 is a plan view of a portion of said machine;

Figs. 8 and 9 are similar views of modified arrangements of the mechanism shown in Fig. 7 and Figs. 10 and 11 are views of parts of perforated sheets for use in connection with said machines or otherwise.

Referring first to Fig. 1 I have shown a tracker board 1, and a music spool 2 and take-up roll 3 for use in connection with a piano player, player piano or like instrument. The tracker board is of a special type or kind having two rows or sets of apertures, 44: and 55, the former being in advance and conveniently made circular in character, and the latter being in the rear and at one side of the front apertures, 1-4: and conveniently in the form of long narrow slots or slits. This special type of tracker board is disclosed and claimed in my Patent, No. 1,206,779, issued Nov. 28, 1916. It is representative of a general type or kind of tracker board designed especially to produce solo effects in tracker board instruments, but doubtless capable of other uses. When used for solo effects the rear apertures 5-5 may be used to set certain mechanism in the instrument so that when the corresponding aperture t is opened a solo efiect may be produced. In this way the apertures 5 5) may be called the solo or accent apertures and the forward apertures 4: the note apertures.

In my Patent No. 1,183,210, issued May 16, 1916, I have shown an instrument capable of operating in this way, but I desire it understood that my present invention in perforated sheets is not of course to be limited to such an instrument or even to such a specific construction of tracker board.

The music sheet 6 carried by the rolls 2 and 8 is provided with two kinds of perforations, 7-7 and 8-8, a portion of said sheet being shown in Fig. The perforations 7-7 are long slots or slits capable of opening only the tracker apertures l4l. The perforations S 8 are slits or slots with laterally extending parts or portions 8"-8 which are capable of opening both apertures 4 and 5 of a note, the part 8 opening the tracker aperture 1 and thcpart 8 opening the aperture 5. Any perforation 8 will obviously open its allotted tracker aperture 5 first, and then the corresponding or associated aperture 4 at a later time, due to the fact that the front end of the perforation S does not reach the aperture t until after it has reached and opened and traveled along the aperture 5. Under some circumstances this is desirable, inasmuch as it permits the apertures 5-5 to be opened appreciably before the corresponding apertures 4i are opened, thus allowing ample time for the setting of the instrument mechanism before the note is sounded. The apertures ll are then opened only for a short time, only suflicient to permit the proper actuation of the note sounding mechanism of the instrument. In Fig. 3 I have shown a modification of this arrangement, consisting of a music sheet 6, having perforations 77 and also perforations 8"8 The latter consist of a long slot with side projections or parts tions 77 of the sheet 6.

B -8, the long slot continually opening the rear or solo port 5 and the side projections 8 intermittently opening the front or note sounding port 4-, so that these perforations 8 8 will cause a solo or accent trill or repetition. In Fig. a I have shown a somewhat different form of perforated sheet 6, and it has perforations 'i'7 similar to the perfora- It also has perforations 10 of zigzag character, consisting of two elongated slots of substantially the same width connected together. The slot 10 is adapted to open the port or aperture of the tracker, and the slot 10" to open the port or aperture 5 of the tracker. In this particular form of sheet the forward edges or ends of the parts or slots 10" and 10" are separated from one another by a distance equal to the longitudinal distance between the rear edges of the ports 4t and 5, so that the front ed 'es of the parts 10" and 1t" reach the rear e lges of those ports at the same time and thus open the two ports simultaneously. This allows the two mechanisms arranged for cooperation with the two ports to be operated simultaneously or in such manne' as may be desired or arranged in connection with the simultaneous opening of he two tracker board ports.

In Fig. 5 I hare shown a portion of a music sheet 6 having a still different arrangement of perforations. In this sheet there are shown perforations 7-7 similar to the perforations 7-7 of the other sheets, and also perforations lk-ll. The latter are constructed with portions 11 which open the rear ports 5, and 11 which open the forward ports a. The forward edges of the parts 11 are situated in advance of the forward edges of the portions li a longitudinal distance less than the distance referred to in connection with the two parts of the zigzag perforation 10 of the sheet 6 of Fig. 4t, that ,0 say a distance less than the longitudinal. distance between the rear edges of the ports f and 5. In this way the rear port 5 will be opened by the part or slot 11 before the forward port '-fl-. is opened by the part or slot 11". Thus whatever desirable result is wished in connection with the opening of said ports, the rear one in advance of the former, as for example the setting of the solo mechanism by the rear port prior to the operation of the note mechanism by the forward port, can be accomplished by perforations like those of this sheet 6.

Thus it will be seen. that in the Figs. 2, 3, 4t and 5 I have shown perforations of what may be called a zigzag type, that is, with laterally displaced portions, and these zigzag portions are longitudinally displaced in various ways with reference to the pairs of tracker board ports or openings. It is obvious that they could be longitudinally displaced with reference to said ports or apertures in other ways according to the result desired, and still come within the scope of my invention.

Referring now to Figs. 6, T and S, I have shown in Figs. (5 and 7 a machine for out ting perforated sheets set forth and claimed. in my Patent No. 1,195,4277, issued AugustQQ, 1916, and in an application Serial No. 578,- 571) filed August '2, 1910, I have set forth and claimed the process of preparing perforated sheets in which said machine may be used, the present application being a division of the latter application which disclosed certain forms of perforated sheets as well as the process of preparing the same. T his machine will not be described in full here, as it seems clear no full description is necessary for the purposes of this application. In brief it will be stated that the machine has a plmrality of sets of styluses or readers, 13 and ll, a pair or set for each note, displaced longitudinally of the direction of trarol of the master sheet 15, (Fig. T). These r *aders are associated with suit able reciprocating mechanism fully disclosed in said other application, and a corresponding number of sets of punches 23 and are n-orided and arranged to be actuated by said reciprocating mechanism, under the control of the readers 1.3 and l t. A plurality of sheets A are arranged in the lower portion of the machine so as to cooperate with and be cut or perforated by the punches and In Fig. 11 I have shown a perforated sheet 6 adapted to be used as a record or master sheet in said punching machine. This sheet is provided with t to sets or kinds of perforations 7 and 10, the former being straight slots, and the latter zigzag. The portions 10 and 10 of the zigzag perforations 10 are displaced longitudinally with reference to the readers 18 and l-l, and in the form of sheet shown the displacement is equal to the longitudinal displacement of said readers, so that the two readers mav enter the zigzag portions of the perforation simultaneously. This, in the form of machine shown, allows the punches to be operated simultaneously, and inasmuch as they are shown longitudinally displaced, the resulting perforations in the sheet A would correspond substantially with the perforations 10. This sheet 6 corresponds, it will be seen, with the sheet 6 of Fig. 4-, the longitudinal displacement of the portions of the zigzag perforations of the sheet 6" being with reference to the readers 13 and 14 whereas the longitudinal displacement of the portions of the zigzag perforations of the sheet 6 is with reference to the tracker board ports or apertures. This displacement can, of course, be varied in the sheet 6 as desired with reference to the readers 13 and 14 in the same way that the zigzag per forations are varied in the sheet 6 relatively to the tracker board ports.

In Fig. 8 I have shown a modified form of the machine of Figs. 6 and 7, which modification is described in my said other application and patents, the readers 13 and 14 being side by side, but the punches 23 and 24: being longitudinally displaced.

In Fig. 9 I show a still different modification of the punching or perforating machine in which the arrangement of readers and punches is reversed, the readers 13 and 14: being separated and staggered, and the punches 23 and 24 being side by side. The use of the sheet 6 of Fig. 10 in the machine of Fig. 8 would result in the formation of the sheet 6 of Fig. 11. The use of the sheet 6 of Fig. 11 in the machine of Fig. 7 would result in the formation of the sheet (3 of Fig. 11. The use of the sheet 6 of Fig. 11 in the machine of Fig. 9 would result in the formation of sheets like 6 of Fig. 10, which latter sheet is provided with perforations 7 and 18, the latter being a wide rectangre lar perforation.

This application, as before stated, is a division of m application, Serial No. 578,579, filed ugust 28, 1910, improvement in process for perforating music sheets.

It will be understood that the perforated sheets disclosed herein are merely illustrative of my invention and that it is not the intention to limit the invention to such specific forms.

WhatI claim is:

1. A perforated sheet for the purposes set forth, having straight perforations, and also having other perforations each of which consists of a plurality of longitudinally extending slots laterally displaced with reference to one another, and connected together end to end.

2. A perforated sheet for the purposes set forth, having straight perforations, and also also having other perforations each of which consists of a plurality of longitudinally extending slots laterally displaced with reference to one another, and connected together end to end, said longitudinally extending laterally displaced slots of said last mentioned perforations being for the same note.

3. A perforated sheet for the purposes set forth, having two sets of perforations, one consisting of straight slots and the other consisting of two laterally displaced slots connected substantially end to end, and having their forward edges separated longitudinally with reference to the longitudinal displacement of the instrumentalities or devices with which the perforated sheet is to cooperate.

1. A perforated sheet of the character specified, having perforations consisting of elongated slots having a plurality of side projections for the same notes as the respective slots.

5. A perforated sheet having perforations of zigzag character.

6. A perforated sheet for the purposes set forth having a perforation comprising a longitudinally extending slot part to control accent and laterally extending projections at the side of said slot to cause repeated note soundings.

7. A sheet of the class specified provided with a perforation having a part adapted to sound a repetition or trill, and also having another part adapted to control accent of the same note during said repetition or trill.

8. A music sheet having a single perforation provided with means for causing repetition.

9. A music sheet having a perforation provided with a plurality of side projections for causing repetition.

In witness whereof, I hereunto subscribe my name this 20th day of Sept, A. D. 1911.
